LUBRICATOR.

SPECIFICATION forming part of Letters Patent N 0. 657,219, datedSeptember 4, 1900. Application filed September '7 1899. Serial No.729,676. (No model.)

To all whom it may concern:

Be it known that I, BYRON J ACKSON, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement in Lubricators; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to a device by which bearings of any descriptionare constantly and automatically lubricated.

My invention comprises details of construction, which will be more fullyexplained by reference to the accompanying drawing, in which the figureillustrates a sectional view of a lubricator embodying my invention.

The object of my invention is to provide a positive means forautomatically and continuously oiling and lubricatingjournals, shafts,loose pulleys, or other revoluble parts by pressure while in motion,such lubrication being effected directly by the revolution of the parts.

A is a shaft, which is herein shown as vertical.

B is a journal box or bearing in which the shaft is turnable, which mayhave the usual or any suitable antifrictional surface or surfaces, as atB.

C is a cup or receptacle for oil having, preferably, a circular orrounded interior. At one end this cup or bowl has a flange or collar D,fitting the shaft, and a set-screw E secures it to the shaft, so thatthe cup is revoluble with the shaft. The other end of the cup is open,the opening having a sufficient diameter, as here shown, to extend overthe journal or bearing B, with the edges of the cup approaching closelythereto without actual contact. Such a cup being filled with oil orother flowing lubricant, it will be manifest that when the shaft is inrotation the centrifugal force will throw the oil outward into thecurved interior periphery of the cup. From this point the oil is forcedby the velocity given it by the revolving cup and is led to the bearingby means of a tube F, one end of which is connected with the journal boxor bearing, so as to convey the oil to the point where it is to be used.This tube F connects with a passage G, which extends upwardly throughthe bearing and discharges into a second cup H, formed integral orconnected rigidly with the upper part of the journalboX. This second cuphas an annular loose cover H,witl1 a central opening through which theshaft loosely passes. The outer end of the pipe F is open and terminatesclose to the inner wall of the revoluble cup, so that the oil orlubricant which is thrown outwardly and carried around within the cup byits revolution will be forced by the velocity or pressure to enter thetube F and pass thence through the passage G to the point where it isdischarged into the upper receptacle, from which receptacle it will'flow through the bearing by gravitation and again return to therevoluble cup below. The inner end of the collar or flange which carriesthe cup projects upwardly within the cup, as shown, and thus forms aninner wall or retainer, around which the body of oil will rest wheneverthe parts are stationary. When the shaft and cup are revolving, thecentrifugal force throws the oil out into the inner wall, where itremains in a comparatively-thin sheet, and as before described, themotion and pressure will cause it to flow through the tube and passageto the bearing, whence it again returns between the parts of the bearingto the cup, thus continually circulating without waste.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

An improved lubricator including a revol u ble shaft, a flange or collarsecured thereto and formed with a cup having a rounded interior andhaving one end open, a second cup surrounding the shaft and a bearingformed rigid therewith and entering theopen end of the first-named cup,but without contacting therewith, and having a passage through it, anannular loose cover for the second cup through which the shaft looselypasses, and a bent tube having its open end lying close to the innerwall of the first-named cup.

In witness whereof I have hereunto set my hand.
